Start Chat Maksutov-Cassegrain are great for visual use or planetary imaging, the views will be full of contrast with a darker background sky due to their long focal lengths. A Schmidt-Cassegrain, which belongs more broadly to the Catadioptric telescope type, uses a folded optical design incorporating both mirrors and lenses to gather and bring the light to focus. 5. Explore Scientific Firstlight Dobsonian Bundles, Angle Adjusters, Adaptive Optics & Field De-Rotators. I can detect down to 20th mag in 5 minutes with a conventional CCD and no filters but at a SNR that's just above my noise floor. For professionals, advanced students, and serious amateurs, standard telescopes designed for night sky viewing have drawbacks that interfere with obtaining highly detailed images, particularly for deep sky objects. ", Even if they decide to get into astrophotography and buy another telescope on an equatorial mount, most Dobsonian owners love their telescope enough to keep it and pull it out whenever they want to experience the cosmos visually.

While you can look through an RC telescope, it is trickier to use visually than other designs. To keep from accidentally doing that, remove the finder scope all together and either replace it with a solar finder, which projects an image telling you when the Sun is in the field of view, or use the telescope's shadow to ascertain when the sun is in the proper location. A catadioptric telescope uses a combination of mirrors and lenses to gather and focus light. Thats because reflecting telescopes use mirrors, which provide more sensitivity to all wavelengths of light and dont cause chromatic aberrations like color fringing. The Samuel Oschin Telescope, a wide-field Schmidt telescope designed for survey work, has a 48-inch (1.2-meter) aperture with a glass corrector plate and a 72-inch (1.8-meter) mirror. You may want to google for "Steven Aggas" or "Apache-Sitgreaves Observatory" in Overgaard AZ. Air Force Maui Optical Station (AMOS) You can watch our video on how to collimate a high-end Ritchey-Chretin here." I have a nice spreadsheet I can send you that takes your detector parameters, star FWHM, aperture, and calculates the signal to noise ratio of a star image for a given exposure time.

Simply put, while a refractor telescope uses lenses to gather light, reflectors use mirrors. Have you watched a piece of paper catch fire when light was shined on it through a magnifying glass? However, if you want to do astrophotography, your Newtonian reflector needs an equatorial mount. The SCT uses a flat-looking aspheric corrector lens on the front end of the telescope which is less expensive than other corrector plates, making the Schmidt-Cassegrain a good value as well. Wearing glasses keeps your eye further away from the telescope eyepiece, and if the eyepiece does not have good eye relief - the distance from the lens to where the image comes to focus - you may not be able to see the object very well, if at all. I am doing research with a 0.4m SCT and an old camera, and while I can do useful work, there's always something interesting that's about a magnitude too faint for my system (or I can detect it but not with enough SNR to get good data).
